[Liripo]

library(echarts4r)

e <- mtcars %>%
  e_charts(qsec) %>%
  e_line(mpg) 
e %>% 
  htmlwidgets::saveWidget(file = "test.html")
webshot::webshot("test.html",file = "test.png")

Cut out is a blank interface.

I'm having the same issues with dygraphs plots on UNIX Centos... both .jpeg & .png

Oddly enough, the plotly plot works for both picture formats on the same system.
